Jennings won't practice Wednesday due to a hip injury, Nick Wagoner of ESPN.com reports.
The hip issue is a new concern for San Francisco's No. 3 receiver, who is coming off a 3-27-0 receiving line (five targets) in last Thursday's 36-24 win over Seattle. Jennings has just seven catches for 128 yards in three games since erupting for a 11-175-3 receiving line Week 3 against the Rams, as he's been operating as the fourth option in San Francisco's passing game ever since Deebo Samuel and George Kittle returned from their respective injuries.
